Compressors Types, Operation & Maintenance

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume or giving velocity .Many compressors can be staged, that is, the gas is compressed several times in steps or stages, to increase discharge pressure. Each stage further compresses the gas and increases its pressure and also temperature . This Course address a detailed knowledge of compressors Describe its :, principals , Glossary ,Terminologies, operation, maintenance (corrective, preventive, predictive) , overhauling criteria , acceptance testing and troubleshooting.
